The first monocarbenepalladium( 0 ) complexes with benzoquinone and naphthoquinone as additional ligands have been prepared. As demonstrated by NMR spectroscopy and X‐ray analysis, the complexes show a unique coordination mode giving quinone‐bridged dimers. The monocarbenepalladium( 0 ) complexes allow efficient cross‐coupling reactions of aryldiazonium salts with olefins (Heck reaction) and arylboronic acids (Suzuki reaction).
